Zane is running the challenge of champions obstacle race at his summer camp. He runs 3/4 of a mile, but then he twists his ankle while going up the mounds of Doom. Zane still has 1/2 of a mile left to run, so he drops out of the race. Which equation can you use to find the total distance d of the race?

1 1/4 miles

Step-by-step explanation:

I don't know a proper equation but here is how I solved it.  1/2 is 2/4 so I added a fourth of that 2/4 to the mile he ran before he twisted his ankle so 1/4 +3/4 = 4/4 or 1 mile. So then adding what's left of the 2/4, you have 1 1/4 = d.

Let me know if I'm wrong

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
